6.5 SPI (serial peripheral interface)
The 8-bit wide programming word (input word, see table 3) is read in via the data input
DI, and this is synchronized with the clock input CLK supplied by the µC. The diagnostic
information depends on the operation mode. The internal latches for the V_bat-stand-by
diagnosis are reseted when leaving this mode.
